Description

  The present invention relates to a handrail with a handrail having a structure in which a handrail rail is disposed at the upper end of a support column provided at intervals on a staircase in which treads are provided stepwise, and a side panel is disposed below the handrail rail.

  For example, a handrail is provided on the stairs, and a panel may be disposed below the handrail for safety. In this case, a configuration is adopted in which two upper and lower body edges are attached under the handrail and the panel is held between these body edges. Since the handrail is supported by the upper part of the pillar arranged along the stairs, if a panel is provided below the handrail, the pillar will cross the trunk edge. I was hitting the support and processing.

  As means for that, it is known that a fitting groove is formed in the support column and an attachment for fitting the end of the panel is fitted into the fitting groove (see Patent Document 1). According to this, since the edge part of a panel is swallowed inside the attachment, the edge part edge is not exposed outside.

Moreover, the support | pillar for supporting a handrail was being fixed to the stairs. In this case, a method of fixing the column directly to a step board of a staircase with a screw or fixing via a fixing bracket is common (see Patent Documents 2 and 3).
